SAW.

SPECIFICATION forming part of Letters Patent N0. 309,646, dated December:23, 188%.

Application tiled May 6, 1884. (No model.)

To all whom it may concern:

Be it known that I, Jiisrnn L. PURPLE, of Owego, in the county of Tiogaand State of New York, have invented a new and Improved Saw, of whichthe following is a full,

I clear, and exact description.

The object of my invention is to provide a new and improved saw which isso constructed that it can also be used as a square, plunib, bevel, 820.

The invention consists in a saw having a longitudinal slot at rightangles to the straight inner edge of the handle, through which slot aset screw passes, which can be adapted to any desired angle, one edge ofthe slot being provided with a graduated angle-scale, while the lowerinner corner edge of the handle is adapted to serve as a rest for astraight-edge, rule, or analogous instrument.

Reference is to be had to the accompanying drawingsiorining part of thisspecification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a side view of the handle end of my improved saw, partsbeing broken out. Fig. 2 is a top view of the same.

The saw-bla le A is secured at its butt-end to a handle, B, in the usualmanner. This handle is provided on its inner end with a straight'edge,which is at right angles to the back edge of the saw, or to alongitudinal slot, G, with the said back edge. A screw, D, is held inthat corner of the handle toward the cutting-edge, and a recess, E, isformed on the upper inner corner, and into the said recess the end ofthe slot passes. The recess E is of such depth that the head of a screw,F, can be held entirely within the recess,so that the said head does notproject be yond the inner straight-edge of the saw-handle. The screw Fpasses through the slot 0, and is adapted to be moved in the same in thedirection of the slot. Along the inner edges of the slot 0 lines arecut,etched, or otherwise produced,which indicate the inclination from zeroto forty-five degrees. In the inner edge of the saw-handle a glasslevel-tube, G, is held. As shown in Fig. 1, the inner edge of the handleB is adjusted at right angles to the slot 0. If a different angle isdesired, the screw l is moved more or less in the direction of the arrowa, and a straight-edge, rule, &c., placed against the heads of thescrews 1) and F have the desired inclination, as shown in dotted linesin Fig. 1. If the saw is placed with its back against an upright, it canbe used as a pluinb, and it" held in a horizontal position it can beused as a level.

I am aware that it is old to provide the blade with a graduated are andwith a pivoted 6o bevel-arm having a bevel-link, said bevelarmregistering with the graduations of said are; to provide the blade withpivoted angular pieces having a clamping-screw adjustable in a straightslot in the blade, and with a grad- 6 nated are, and to provide theblade with pivoted bevclbeams having a clamping-screw adjustable in asegmental slot in said blade, and with a graduated arc.

Having thus described n1 y invention, I claim as new and desire tosecure by Letters Patent- The combination, with a saw with its bladeprovided with a straight longitudinal slot, along one edge of which arearranged anglegraduations,oftl1e set-screw adjustable in said 5- slot,and adapted to serve, together with the lower inner corner edge of thehandle, as a rest for a straight-edge, rule, or analogous instruinent,substantially as set forth.
